Hopefully you are doing well? I just was reading a new article, just posted an excerpt above.
I'm pretty good at present, thanks - had a serious flare-up at the end of November that turned me into a shivering, shaking, trembling wreck - a mass of 'fasiculations' (muscle twitches); also sore neck, brain fog, and mild inner ear dizziness & disorientation. I spent a night in hospital having every test & scan under the sun (including lumbar puncture). All they found was low vitamin B12, so they gave me a jab of it and kicked me out. Since then it's been a slow recovery. I suspect it's an inflammatory (immunological?) condition affecting the CNS, which was probably exacerbated by low vit.B12. It tends to come on following physical stress - e.g. overdoing exercise, but can come on in minutes, last a few hours, and then go from feeling really rough back to fairly OK in half an hour, so unlikely to be lingering virus.
No psychosis, but I did notice that it affected my mood and preferences, so that my viewing & reading preferences changed while I was unwell. My visual short focus has become much worse - I now need reading glasses, and I tend to misinterpret brief events at the periphery of my vision, so that reflections, shadows, floaters, etc., catch my attention as something moving more than usual; indications of CNS involvement. It's a bit odd, but now I know I'm otherwise physically in good order, it doesn't bother me too much.
I'm taking a fairly high dose (4,000IU) of vit.D, as an immunological modulator for Covid protection, but it may be helping this problem too...
But really, I think I've been lucky - there were people in much worse trouble than me in hospital - the guy opposite me in the hospital ward had a liver transplant and was a little psychotic and understandably terrified of catching Covid - which wasn't helped by the patient next-but-one from him testing positive and being moved out, after which we were all given 14 days isolation notifications... Dangerous places, hospitals!
